Monster Cookie Bars
Description
Monster Cookie Bars blend several classic cookie ingredients—peanut butter, quick oats, white and brown sugars, and eggs—resulting in a moist and chewy texture. The dough is mixed until just combined to maintain softness after baking. Chocolate chips are folded into the batter, while M&Ms pressed on top add color and a contrasting crunch once baked. The bars bake at 350°F for only 15 minutes to keep them soft rather than fully set, which is why they may look underdone before cooling.
These bars can be cut and served as a snack or dessert and can be packed for lunchboxes or casual gatherings. The peanut butter provides rich flavor and moisture, while the oats add texture and heartiness. The combination of melting chocolate chips inside and the crisp M&Ms topping creates a multi-textured bite.
Leftover bars can be stored at room temperature for several days separated with parchment paper to prevent sticking. Refrigeration extends their shelf life to a week, and freezing up to three months is also possible when individually wrapped. Variations include substituting peanut butter chips for chocolate or swapping M&Ms with Reese's Pieces for more peanut butter flavor.
